AI Technical Summary

Benefits of technology

The present invention is about a display device that can improve its reliability and stability. The device includes an uneven part on the bending area of the upper substrate, on which a touch sensor is placed. The uneven part has uneven surfaces along its length, which prevents cracking or disconnection of the routing lines during bending. This results in improved reliability.

Problems solved by technology

However, the flexible display device is subjected to stress due to such bending or folding.
Thus, disconnection or cracking may occur at routing lines of the touch screen that are arranged in the bending area, on which stress is concentrated, thereby deteriorating reliability and stability.

Embodiment Construction

[0019]Reference will now be made in detail to the aspects of the present disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0020]FIG. 1 is a cross-sectional view of a display device having a touch sensor according to the present disclosure.

[0021]The display device having the touch sensor depicted in FIG. 1 includes a cover film 260, a flexible display panel 200, and a back plate 280.

[0022]The cover film 260 is disposed to cover the front surface of the flexible display panel 200 using an adhesive layer 250, and protects the flexible display panel from external shocks. The cover film 260 is formed of tempered glass, which includes at least one of sapphire glass and Gorilla glass, or is formed of a plastic material, which is any one of polyethylene terephthalate (PET), polycarbonate (PC), polyethersulfone (PES), polyethylene naphthalate (PEN),...

Abstract

Disclosed is a display device capable of exhibiting improved reliability and stability. The display device includes an uneven part, which is disposed on a bending area of an upper substrate, on which a touch sensor is disposed. Therefore, each of routing lines disposed on the uneven part has an uneven surface that is formed along the uneven part within the bending area. Accordingly, cracking or disconnection of the routing lines is prevented during bending of the display device, and consequently reliability and stability are improved.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Korean Patent Application No. 10-2017-0057311, filed on May 8, 2017, which is hereby incorporated by reference in its entirety as if fully set forth herein.BACKGROUNDField of the Disclosure[0002]The present disclosure relates to a display device, and more particularly to a display device capable of improving reliability and stability.Description of the Background[0003]A touch screen is a type of input device that allows a user to input a command by selecting an instruction displayed on a screen of a display device with a hand or using an object. The touch screen converts a contact position, which is directly contacted by a user's hand or an object, into an electrical signal, and receives the instruction selected at the contact position as an input signal. Such a touch screen can eliminate a separate input device, such as a keyboard, a mouse, or the like, which is connected to a display device, thereby...
